Psychometrics in Practice at RCEC [PDF]
, 2012 A broad range of topics is dealt with in this volume: from combining the psychometric generalizability and item response theories to the ideas for an integrated formative use of data-driven decision making, assessment for learning and diagnostic testing.

Unidimensionality in Rasch Models: Efficient Item Selection and Hierarchical Clustering Methods Based on Marginal Estimates [PDF]
arXiv, 2023 A strong tool for the selection of items that share a common trait from a set of given items is proposed. The selection method is based on marginal estimates and exploits that the estimates of the standard deviation of the mixing distribution are rather stable if items are from a Rasch model with a common trait.

Clustering South African households based on their asset status using latent variable models [PDF]
, 2014 The Agincourt Health and Demographic Surveillance System has since 2001 conducted a biannual household asset survey in order to quantify household socio-economic status (SES) in a rural population living in northeast South Africa.

Invariance of Comparisons: Separation of Item and Person Parameters beyond Rasch Models [PDF]
arXiv, 2023 The Rasch model is the most prominent member of the class of latent trait models that are in common use. The main reason is that it can be considered as a measurement model that allows to separate person and item parameters, a feature that is referred to as invariance of comparisons or specific objectivity.

Hybridisation in two-band Hubbard models with different bandwidths [PDF]
J. Phys.: Condens. Matter 19, 436206 (2007), 2007 We investigate the orbital selective Mott transition in two-band Hubbard models by means of the Gutzwiller variational theory. In particular, we study the influence of a finite local hybridisation between electrons in different orbitals on the metal-insulator transition.

Validating the parental reflective functioning questionnaire ‐ infant version using a rasch model
Infant Mental Health Journal: Infancy and Early Childhood, EarlyView.Abstract Parental reflective functioning is the parent's ability to reflect on the psychological processes in their child and in themselves as a parent. Recently, an infant version of the Parental Reflective Functioning Questionnaire, PRFQ‐I, has been developed and validated using confirmatory factor analyses.

A Nonparametric Bayesian Item Response Modeling Approach for Clustering Items and Individuals Simultaneously [PDF]
arXiv, 2020 Item response theory (IRT) is a popular modeling paradigm for measuring subject latent traits and item properties according to discrete responses in tests or questionnaires. There are very limited discussions on heterogeneity pattern detection for both items and individuals.

ReHabgame A non-immersive virtual reality rehabilitation system with applications in neuroscience [PDF]
Heliyon. 2018 Feb 12;4(2):e00526, 2018 This paper proposes the use of a non-immersive virtual reality rehabilitation system ReHabgame developed using Microsoft Kinect and the Thalmic Labs Myo gesture control armband. The ReHabgame was developed based on two third-person video games that provide a feasible possibility of assessing postural control and functional reach tests.

Rasch mxture models for DIF detection: A comparison of old and new score specifications [PDF]
, 2013 Rasch mixture models can be a useful tool when checking the assumption of measurement invariance for a single Rasch model. They provide advantages compared to manifest DIF tests when the DIF groups are only weakly correlated with the manifest covariates ...

Don't Tie Yourself to an Onion: Don’t Tie Yourself to Assumptions of Normality [PDF]
, 2012 A structural measurement model (Adams, Wilson, & Wu, 1997) consists of an item response theory model for responses conditional on ability and a structural model that describes the distribution of ability in the population.
